The movie i remember Val Kilmer most for is Real Genius (1985)
I like it because of how nerdy cool geek it was.
The next is The Saint (1997)
I really enjoyed all the characters he played in the movie.
And, of course, Batman Forever (1995)
because, Batman
And, like you, Tombstone is one my top favorites.
I wish that Val Kilmer had more good years.
